It has a function "group_exists" and if it exists it is supposed to be
listed in +PREEXISTING. I see you have those above.
That file should contain the name of package that created it.
Looks like the problem is in CHECK-REMOVE action in
mk/pkginstall/usergroup -- it doesn't check the +PREEXISTING.
I think it could still give the current message plus mention that the
group (or user) existed before any package was installed.
